58303786 ÷ 258 
Our goal is to divide 58303786 by 258.

Advancing to step 1:
258 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 258

Going ahead to step 2:
258 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 258

On to step 3:
258 can be fit into 583 2 times, resulting in a remainder of 67.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 516 from 583 leaves us with 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 258

Going ahead to step 4:
When dividing 670 by 258, we get 2 with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 516 from 670 and we're left with 154.
Grab the next digit (3) from the dividend, add it to 154, then carry on: 1543 / 258

Advancing to step 5:
1543 divided by 258 is 5 with a remainder of 253.
Use 5 as the next digit of our solution. 
Result so far: 225.0
Subtract 1290 from 1543 to get 253.
Append the next digit (7) from the dividend to 253 and continue with: 2537 / 258

On to step 6:
258 can be fit into 2537 9 times, resulting in a remainder of 215.
The number 9 becomes the next digit in our result. 
Result so far: 2259.0
Subtracting 2322 from 2537 leaves us with 215.
Include the next digit (8) from the dividend after 215, then repeat: 2158 / 258

Advancing to step 7:
When dividing 2158 by 258, we get 8 with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 22598.0
Subtracting 2064 from 2158 leaves us with 94.
Bring next digit (6) of the dividend behind the 94 and repeat the process: 946 / 258

Let's proceed to step 8:
258 goes into 946 3 times with a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 225983.0
If we take 774 away from 946, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 9:
When dividing 1720 by 258, we get 6 with a remainder of 172.
Record the quotient 6 as the next digit in the result. 
Result so far: 225983.6
If we subtract 1548 from 1720, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
If we divide 1720 by 258, we get 6 and a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 225983.66
Deduct 1548 from 1720 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Our division results in 225983.66 with a remaining 0.172.
